The invention discloses an oil well shaft deposition experiment device and an operation method, and relates to the technical field of shaft deposition experiments. One end of the experiment pipeline is connected with the air compressor through a pipeline, and the pipeline is provided with an inlet flange valve and an air compressor valve; the buffer tank is connected with the other end of the experimental pipeline through a pipeline, and an outlet flange valve and a primary pressure reducing valve are mounted on the pipeline; the oil-gas-water three-phase separator is connected with the buffer tank through a pipeline; the simulation experiment device can simulate multiple on-site multiphase and single-phase flow working conditions in a wellbore, firstly, a single-phase wellbore pipe flow wax deposition experiment can be conducted, secondly, oil-water, oil-gas and oil-gas-water multiphase wellbore pipe flow can be achieved, flexible adjustment of the proportion of different components can be achieved, and the
